IMPORTANT

Version 6.7.x requires an .htaccess file with additional rewrite rules compared to version 6.6.x. If you upgrade, make sure you properly deploy the included sample.htaccess file. Otherwise the REST API will not work.

Emails are being sent in chunks (50 by default) in order not to overload/spam the outgoing SMTP server

UI

Ui cleanup in several sections

Inlined fields in Forms

Cleaned up LESS files.

Strengthened upgrade script. Note: If you interrupted a previous upgrade before it completed, you MUST restore a clean backup. Continuing to run with a half upgraded DB is plain DB abuse. If you do this, we don't promise anything. However, the upgrade script now does more attempts than ever before to help you recover if you feed it a previously abused database.
